Abstract

PURPOSE: To obtain a display tube capable of bright fluorescent display in static driving system by arranging in the from of coating each segment anode at a position projecting higher from, through insulation layer, the coated position of an anti- electrification layer and increasing its anti-electrification effect.
CONSTITUTION: On the upper surface of a base plate 1, wiring film 2, insulating film 3, and anti-electrification layer 14a are formed in a laminated form. On the upper surface of the insulating film 3 of the parts where each segment anode 5a is in a coated form, arranged an insulating layer 21 is coated wholly, and on the insulating layer, anode 5a and fluorescent layer 6a are laminated. Accordingly, the anode 5a is arranged and projected higher on the upper surface plate side 11 at least by the thickness of the insulating layer than the upper surface of the anti- electrification layer 14a. As the insulating layer 21 and the insulating membrane 3 are connected, the length of the connection wire of wiring film 2a and anode 5a which connection wine passes through the anti-electrification layer 14a, is reduced. Thus, anti-electrification effect is increased, so a fluorescent tube which is capable of developing bright fluorescent display in static driving system can be obtained.
